Just out of curiosity are you on an hdmi connection? I have had issues with my premiere from time to time not negotiating the audio correctly with my receiver. Video is fine and it does not affect all recordings. This seems to happen the most when switching back and forth between podcast downloads and 5.1 DD recordings.

My fix in this scenario is to switch my receiver to another input and then back to the TiVo and voila the hdmi does a re-handshake and "magically" audio has returned. Prior to this the receiver indicated it was not receiving audio. If you do not have a receiver it may be worth your while to switch the tv input to something else and then back.

Last week the sound cut out about a minute into GoT (during previews) and the silence also hit all of Veep that followed.

This week the whole GoT recording was silent, but Veep was fine.

I don't see how HDMI could be a factor. The recordings I have on disk are constantly silent, it's not a transient playback issue. The HDMI devices connected to the output are just not a factor at record time, and an HDCP problem at playback time would affect the picture as well as the sound.
